USE :

UV-292 liquid hindered amine light stabilizer which is widely used to improve the weatherability of a variety of polymers. UV-292 is highly effective used for a wide range of polymers and applications including polyurethanes,sealants, adhesives, PMMA , elastomers, unsaturated polyesters, acrylics, vinyl polymers(PVB,PVC). It’s especially applied in polyurethane , because it has good compatibility in solvent

Hindered amine light stabilizer,mainly used in paints and printing ink,especially developed for coating. It’s efficiently provides significantly extended life time.
